Carbon-epoxy composites are being increasingly used in structures requiring high specific strength and stiffness. After damage, repair of these structures should be evaluated, instead of their disposal, for cost saving and ecological reasons. This book deals with the numerical strength prediction with cohesive zone models and experimental validation of adhesively-bonded repairs in carbon-epoxy laminates. Single and double-strap, and also scarf repairs, were examined under tension, compression and bending loads. Repair of wood structures with composite patches is also proposed for three common...

In many high performance structures, unions between composite materials with other light metals such as aluminium are required, for purposes of structural optimization. This book deals with the experimental and numerical study of single lap joints, bonded with a brittle and a ductile adhesive. These are applied to hybrid joints, between a high strength aluminium alloy and carbon fibre reinforced plastic adherends, with different overlap lengths. The Finite Element Method is used to perform detailed stress and damage analyses allowing to explain the joints' behaviour and the use of cohesive...
